I use Lexar 512GB professional silver SE CFexpress Type B memory card in my R5 MII. I randomly encountered card full error, only with the CFE card so far, even though the card was just formatted or the camera had been used hours before. I tried power off and on, re=inserting the battery and re-inserting the card but nothing worked. The camera worked fine after replacing the CFE with an SD card. I thought it was a card; so it was returned for a replacement of the same type. I've used the second CFE card and haven't encountered the issue again until on a recent camping trip. So it seems like an issue with the camera instead of the card.
I do vaguely remember only encountering this card full issue in about freezing environments. So, it seems like the R5 II may have an issue with operating in cold environments with the CFE cards? Is this issue known? I tried searching but no relevant results.
